From generation to generation, since 1939, "The Wizard of Oz" brings together children and adults.
Now a study from the University of Turin (Italy) has also concluded that it is the most influential film in film history.
Ignoring box office data or even the positive reviews they received, a computer program treated movies as segments of a network, measuring how they related to each other.
The idea is that films with the greatest cinematic impact would inspire artistic references in other titles that were produced next.
In the immediately following places were "Star Wars" (1977) and "Psycho" (1960). All TOP 20 films predate 1980 and half before 1940.
Most are from the US too, but this is not surprising: analysts have studied 47,000 movies through the Internet Movie Database (better known as IMDB), warning that it is heavily biased towards Western countries.

Using the same system of references between films, the study also calculated a network of influences between filmmakers.
Here, TOP 20 begins with George Cukor, Vitor Fleming (director of "The Wizard of Oz"), Alfred Hitchcock, Mervyn LeRoy and Steven Spielberg. In 13th, the only filmmaker who started making films after 19080: James Cameron, "Terminator", "Avatar" sagas and "Titanic" champion.
Since older films have a tendency to be better positioned in the ranking than newer ones, other criteria have been used to avoid these effects of time.
Taking the titles that were the 15% of the most influential per year until 2010 and giving its directors gold, silver and bronze "medals" as in the Olympic Games, those who had artistically more productive careers were discovered and the list became more diverse : Hitchcock leads clearly to 10th place Spielberg, Brian De Palma, Howard Hawks, John Ford, Martin Scorsese, Ingmar Bergman, Stanley Kubrick, Gerald Thomas and Ishirō Honda.
The study is vast and can be read in the article published in this link.
